APPARATUS FOR MANUFACTURING AERATED WATER.

SPECIFICATION forming part of Letters Patent No. 403,117, dated May 14, 1889. 7 Application filed May 25,1887- Serial No. 239,364. (No model.) Patented in England September 29, 1885, No. 11,567.

I clear, and exact description thereof.

This invention has for its object to allow of the water used in the manufacture of aerated waters and other similar beverages being charged with carbonic-acid gas or other gas,

and likewise cooled, if desired, before being pumped into the condenser. To effect such object I have invented an improved apparatus, which, with the aid of the accompanying drawings, (whereon similar letters of ref,-

erence indicate corresponding parts,) I will now proceed to particularly describe.

Figure 1 is a View in sectional elevation of the aerating-tank. Fig. 2 is a plan view of such tank with the lid removed, so as to show the perforated tray D and rose-pipe E. Fig. 3 is a detail View of the perforated annular connecting-pipe B, and Fig. 4 is a view in sectional elevation of the aerating-tank fitted with a cooler. Fig. 5 is amodification of my device.

Such apparatus consists of a cylindrical or other conveniently-shaped aerating tank, S, made of enameled cast-iron or any other suit able metal or material, closed at the bottom and open at the top, the latter being fitted with a movable air-tight cover, L. Such tank is fitted with a water-supply pipe, 0, terminating at its upper endin a perforated rose pipe, E. A perforated tray, D, provided with a rim or flange, is fitted to such water;supply pipe by means of a collar fixed round the pipe; or such tray may be supported on small brackets fixed to the sides of the cylinder or secured in any other convenient manner. If desired, such tray may also be fitted internally with one or more strainers, d, made of wire-gauze or other suitable material. Sin1ilar additional strainers, (1, may also be placed underneath such tray, if requisite, at suitable distances apart. A ball-cock, F, or other suitable valve arrangement, is fitted to the Water-supply pipe, either at the bottom or in any other convenient position, in order to regulate the water-supply.

A is a supply-pipe, connected at one end to the gas holder or generator (which may be of any suitable description) and having its other end either connected to or terminating in a circular perforated pipe, B, fitted in the bottom of the tank.

G is the gas-outlet pipe, and H the wateroutlet pipe. Both these pipes are connected to the pump or pumps.

Suitable sight-holes, V, are made in the tank,- or, in lieu of or in conj unction with such sight-holes, a suitable water-gage, Z, may be fitted to the tank externally, to indicate the height of the liquid therein.

J is a tap fitted to the top of the tank for emptying and flushing the same.

X is a stand where-on the tank is mounted.

Y is a cooler or refrigerator, preferably made of wood and lined with metal, with which the tank may be either wholly or partly surrounded, tlie intervening space being filled with ice or other refrigeratory material, P. WVhen the apparatus is so fitted with a cooler, the gas and water supply pipes may be fitted at the bottom of the tank, as shown in Fig. 4, and a water-gage substituted for the sightholes, as already mentioned.

R is a draw-off tap fitted to the cooler, so as to allow of the same being drained.

The operation of my invention is as follows: The water enters the tank S through the supply-pipe C, and, passing through the rose-pipe E, falls into the perforated tray D, from whence it again descends in a finely-divided spray or shower to the bottom of the tank until the supply is cut off by the rising water acting on the float-valve F or its equivalent. At the same time the gas enters the tank through the supply-pipe A and perforated circular pipe B, the latter being now immersed in water and ascending through such Water becomes partially dissolved in its passage and fills the upper part of the tank. The gas is then drawn through the outlet G by the action of the pump, while the outlet-pipe H conducts the saturated water to the pump. By this means the water is caused to fall in a finely divided spray or shower from the rose and perforated tray through the meshes of the gauze strainers (if the latter be used) for a considerable distance (such distance being regulated by the height of the aerating-tank) through an atmosphere of carbonic-acid or other gas, and so becomes saturated or charged with the gas. The tank may also, if desired, be fitted with a cooler in the manner above described, or the tank may be used without such cooler. The various pipes may likewise be fitted with suitable stop-cocks when required. Another modification. of my invention (which is illustrated at Fig. 5 of the accompanying drawings) consists in fitting the ball-valve or its equivalent in an auxiliary tank or cistern, G standing on the same level as the aerating-tank and connected by a pipe, Q, thereto. This auxiliary tank may be either open or closed at the top, while the water-supply pipe G rises from the float-valve to near the top of the aerating-tank, where it enters the same and terminates in or is fitted with a rose-pipe, E. The perforated tray D may be carried on a bracket, N, or fixed in any other convenient manner. The other parts of the apparatus do not require to be modified.

I would here observe that I do not confine myself to the precise details of fitting and arrangement hereinbefore specified and shown, as the same admit of variation without de' parting from the nature of my invention.

The advantages of my invention may be briefly summarized as follows:

First. The water being already charged with gas to a considerable extent when pumped from my apparatus into the condenser, a sharper and better charged water is obtained than is practicable under the old process.

Secondly. The amount of power required for pumping is reduced.

Thirdly. \Vhen fitted witha cooler, the water is rendered capable of dissolvingthemaximum amount of gas, at the same time that the resulting beverage is cooler and more agreeable.

Having now particularly described and ascertained the nature of my said invention and A, connected therewith, the gas-outlet pipe G, 5 5

located at the top of the said tank S, the water-outlet pipe l'l, located at the bottom of said tank, the air-outlet pipe or tap J, located on top of the aforesaid tank S, and the outletpipe K, connected with the bottom of the said tank S, substantially as shown and described.

2. In a water-aerating apparatus, the tank S, containing the water-supply pipe C, connected with the float-valve F, the rose-pipe arranged on the end of said pipe 0, the tray D, suspended within the said tank S, the strainer cl, placed within said tray D, the strainer cl, located beneath the said tray D, the perforated gas-pipe B, connected with the pipe A, the sight-hole, the gas-outlet pipe G, connected with the top of the tank S, the water-outlet pipe H, connected with the bottom of said tank, the air-outlet pipe J or tap, connected with the top of said tank S, and the outlet-pipe K, connected with the bottom thereof, in combination with the cooler Y, substantially as shown and described.

3. The combination substantially as shown and described, consisting of the tank S, 0011- taining the water-supply pipe C, terminating at its top end with the rose-pipe E, the floatvalve connected with said pipe 0, the tray D, containing the strainer d, the strainer d, located beneath said trayD, the perforated gaspipe B, pipe A, sight'hole V, the gas and air outlet pipes G and J, located on top of the tank S, and the water-outlet pipes 11 K, connected with the bottom thereof, the whole forming a complete apparatus.

In testimony that I claim the foregoing I have hereunto set my hand this 9th day of March, 1887.
